This piece was a previous step that I took in my optical research. This is, synthetic photography (vs synthesis image). It consists of obtaining the rendering through a modeled camera, collecting with the orthogonal camera of the renderer engine the image that is formed in the negative. The negative should be a chemical description but as we all know, animations and productions are visual and only attend to physics. Chemistry, sound, etc, are not connected, ... still. These are the lenses of an Olympus 150mm camera objective. It consists of seeing the process by which the image is formed. For this an atmosphere and a close light has been used. The plane where the image is inverted is perfectly appreciated, below. Sadly I lost the original information of this scene and only can offer a JPG format...
